CASTER FOBZTU'BULAR LEGS F63 FURNITURE.

To all whom it may concern:

Be it known that I, ALBERT B. Diss, a citizen of the United'States, residing at Newark, New Jersey, have invented certain new and useful Improvements in Casters for Tubular Legs for Furniture, of which the following is a specification, (Case 3,) accompanied by drawings.

The invention relates to the class of casters having sockets for receiving, supporting and holding the caster" pintles within relatively large tubular legs which the casters are designed to su. port. It is customary to secure around t ie foot of tubular legs or to cast thereupon an annular ornamentation or or nainental collar which is-terined a leg mount.

The object of. the present invention is to produce an improved caster structure having a detachable socket adapted to fit within and be retained by the tubular ieg and a leg mount which with the pintle of the caster is secured by such socket to the leg and preferablv serves as a means for relatively centering the pintle and'the foot of the leg.

in the accompanying drawings Figure l isa side view, partly in central section, show ing one preferred embodiment of the inven- Fig. 2 is a side elevation of a socket member used in the construction shown in Fig. Fig. 3 is a cross section of the same Fig. 4 is a detail view of the pintle and the leg mount, the latter in section. Fig. 5 is a view of a variation of the details shown in Fig. 4.

A portion of the tubular leg is'shown at L with a caster embodying the invention inserted and held therein; \V is the wheel; J the jaws; P the pintle of the caster; S is the socket which is shown in the form of a s ring socket of well known type, preferab y of steel; and I Wish it to'be understoodthat various formsof spring sockets may be selected in cerr ing out the invention. The spring socket is detachable from the intle and has flanges F at the lower end which engage the end of the leg and prevent the socket being thrust in too far when they come against the end of the leg. The socket is made of sheet steel and is bowed or barrel shape slightly, as shown, the slits H facilitating this. The socket its the leg tightly and is held firmly in place by the friction against the inner We. 1

oi the log. It is slightly bowed or barrel shape to afford sufficient resilience to the Specification of Letters Patent.

frame to enable it to fit the sli htly varying internal diameters of the tubu ar legs of the size for which it is designed. The two halves of the spring socket preferably have bearings against each other at the points V V to increase the stiilness and strength. The intle P is thrust into the socket and is held t ierein by the spring'arms or leaves T which receive and engage the head and neck of the pintle, as indicated by the dotted lines in Fig. 4. The head of the pintle is centered by the frame S relatively to the tubular leg. The lower end of the. pint-1e is provided with a leg mount M of a-size to surround and approxiinatelyfit the leg L, as shown in Fig. 1.. It also fits and is centered by the intle P. It

is retained. from being accidenta ly drawn off the pincle when the caster is not in the leg by means of cars or lugs E which are punched or otherwise formed on the surface of the pintle. The collar C, which may be either integral with or loose upon the pintle P, forms a shoulder that supports the leg mount Preferably the entire weight of the leg rests upon the disk portion of the leg mount and is transmitted to the collar 0 and thence to the jaws J instead of having the weight of the leg hang upon the socket S and be transmitted therefrom to the head of the pintle P. But in the more generic aspect of the invention I do not Wish to be limited to the form of socket nor to the other exact details (lo-- -or other strong metal, is shown underl ing and strengthening the leg mount M, w ch may be of" relatively soft and weak brass.v

Suchvariations do not, of course, affect the substance of the invention.

In using the caster the socket'is first thrust into place in the l g, usuall separately from the intle, in which case t e pmtle is afterward; thrust into place, its head passing between and being retained bythe springs Tso as to secure it to the socket and prevent its dropping out, while the leg mount M- at the lower end passes over and embraces the end of the leg so that the caster is'held and substantially centered in the leg andlis adapted to support the Weight and strains that may conic upon the leg.
